Title: Air cleaner
Inventor: SHIBUYA AKIRA
IPC: B03C3/00
Filed: 1986-11-27
Abstract: PURPOSE:To prevent deposition of ultrafine particles on an air flow plate by impressing a 3-phase AC voltage to 1st, 2nd, 3rd fine wire-shaped electrodes provided to the air flow plate to form a shifting electric field. CONSTITUTION:The 1st, 2nd, 3rd electrodes 1, 2, 3 arranged with plural fine wires in parallel are laminated on each other via insulating layers. Open pores 4 for allowing flow of air are provided to the centers of the meshes formed by said fine wires, by which the air flow plate 5 is constituted. Arced alternating electric lines of force of a phase-shifting type are formed between the respective electrodes when the 3-phase AC voltage is impressed on the electrodes 1-3. the ultrafine particles and bacteria in the air are transferred in the forward direction of the 3-phase AC when the air is sent in this state toward the air flow plate 5. As a result, only the clean air passes the pores 4. The deposition of the ultrafine particles on the air flow plate 5 is thus obviated and the propagation of the bacteria is prevented.

Title: Light generating circuit for flash lamp
Inventor: NAKAJIMA YASUHIRO
IPC: H02H3/04
Filed: 1990-10-18
Abstract: PURPOSE:To enable a flash lamp to surely make light emitting operations by making a gate voltage which becomes the trigger of a thyristor for light emitting operations higher and making a large electric current to flow in the moment the thyristor for light emitting operations is conducted. CONSTITUTION:When an accidental current flows to the primary side of a current transformer CT, an accidental current corresponding to the current ratio flows form R3 to ZD2 and from VR1 to C3 through R4 on the secondary side, the voltage at a point P2 becomes constant, and the voltage at another point P3 gradually rises. When the potential at the point P3 becomes higher than that at the point P2, a thyristor SCR2 for applying gate voltage is conducted. When the thyristor SCR2 is conducted, the electric charges accumulated in a capacitor 3 for applying gate voltage are discharged through the thyristor SCR2 and a voltage which is higher than the conventional lowest gate voltage is applied across the gate terminal of a thyristor SCR1 for light emitting operations. As a result, the electric charges accumulated in a capacitor C2 for light emission are discharged to a flash lamp 4 and the lamp 4 emits light.

Title: Magnetic disk device
Inventor: MOTOYOSHI KUNIHIRO
IPC: G11B21/02
Filed: 1987-11-09
Abstract: PURPOSE:To prevent the vibration of a positioning mechanism in a magnetic head positioning system by fitting a constraining tool to a base stand by opening the gap in the size equiv. to a small range in the space with at least one of assembling bodies. CONSTITUTION:Either one part of an actuator assembly body 2 or spindle assembly body 1 or both of assembly bodies are mounted so as to freely move in a small range for a base stand 3. In order to move it in a small range like this the constrainer 4 for constraining one or both assembly bodies to the base stand 3 is fixed by fitting to the base stand by opening the gap in the size equiv. to a small range in the space with the assembly body. Due to the assembly body being made to be able to move freely in a certain range for the base stand the vibration energy is absorbed by their rubbing and abutting mutually, hence a damping action is obtd. The need for using another damping mask is thus eliminated and the unnecessary vibration can be prevented without increasing any weight.

Abstract: PURPOSE:To conduct optimal maintenance operation by installing a maintenance- information history memory storing the maintenance information of a printer and mounting a control circuit for the memory, a write switch, a read switch and a printing-data control circuit. CONSTITUTION:When a power supply is turned ON first in a printer device, a maintenance-information history memory control circuit 4 clears all addresses of a maintenance-information history memory 5 (nonvolatile) to zero.

The circuit 2 transmits the content of the memory 5 over a printer 3, and the printer 3 prints the content of the memory 5. Accordingly, since maintenance information is printed to its own printer 3, the maintenance operator determines the history of maintenance operation, and conducts maintenance operation under optimal conditions.
